Next 28 bytes are god-knows what, but I'm thinking the comment date
has to be in here somewhere as PowerPoint knows what time the comment
was added.
01 00 00 00 d6 07 01 00 02 00 18 00 10 00 0e 00
34 00 d4 01 0a 00 00 00 0a 00 00 00
Disassembling this a bit:
First four bytes:
01 00 00 00 = 1 (comment number? It was 2, 3, 4 on the next three
comments.)
Next 16 bytes is a datetime structure:
d6 07 = 2006 (year)
01 00 = 1 (month, January)
02 00 = 2 (day of week? comment was made on Tuesday.)
18 00 = 24 (day of month)
10 00 = 16 (hour)
0e 00 = 14 (minute)
34 00 = 52 (second)
d4 01 = 468 (milliseconds??)
0a 00 00 00 ?
0a 00 00 00 ?
Does this look about right? I've never seen an application store dates
in such a fashion. As ACSII, yes... as 64-bit little-endian numbers,
yes... but not like this.
The last two integers seem to be identical on all the comments I tested
today (actually, every comment has different values, but the two values
were equal to each other) but I've seen them being different on my
original test comments. I can't immediately see what they mean, but
perhaps this data can just be left sitting around as a byte[] once the
other data is parsed out.
Knowing my luck, HSLF already has some logic somewhere for converting
this structure into a Java date and I just wasted my time. ;-)
I probably should bring this thread over to the dev list anyway, huh...
most of the people here probably don't care about how PowerPoint stores
its wacky dates. :-)
